[0026] The heating assembly 2 includes a main air flow pipe 201, a flow distribution pipe 202, an annular heating pipe 203, and an air inlet 205;

[0027] The main airflow pipe 201 is distributed on one side of the drying tank 101, and a plurality of branch pipes 202 are provided. The plurality of branch pipes 202 are evenly distributed vertically and fixed on one side of the main airflow pipe 201 and penetrate into the drying tank 101.

[0028] The annular heating pipe 203 is distributed inside the drying tank 101 and is connected to the shunt pipe 202. The air inlet 205 is provided at the bottom of the annular heating pipe 203. External hot air is injected into the drying tank 101 through the channel formed by the main air flow pipe 201, the shunt pipe 202, the annular heating pipe 203 and the air inlet 205, so as to heat the material inside the drying tank 101.

[0029] The heating assembly 2 also includes an arc-shaped connecting pipe 204;

[0030] There are multiple groups of annular heating tubes 203, and the multiple groups of annular heating tubes 203 are evenly distributed inside the drying tank 101 along the vertical direction;

[0031] Each group of annular heating tubes 203 includes a plurality of annular heating tubes 203 with inner ring diameters decreasing in sequence, and the plurality of annular heating tubes 203 are sequentially distributed from the inner limit, and an arc-shaped connecting tube 204 is fixed to the top of two adjacent annular heating tubes 203 and is in communication with the two annular heating tubes 203, so as to realize the circulation of hot gas in the plurality of annular heating tubes 203;

[0032] The stirring assembly 3 includes a driving motor 301, a rotating shaft 302, and an L-shaped stirring blade 303;

[0033] The driving motor 301 is installed at the center of the top of the drying tank 101, the rotating shaft 302 is fixed to the output end of the driving motor 301 and penetrates into the drying tank 101, and the L-shaped stirring blade 303 is fixed to the outside of the rotating shaft 302;

Each group of L-shaped stirring blades 303 includes multiple L-shaped stirring blades 303 with increasing horizontal lengths, and the multiple L-shaped stirring blades 303 are distributed in a ring shape.

[0035] In this embodiment: it should be supplemented that: the exhaust port 102 is connected to the input end of the external dehumidifier through a pipeline, the output end of the external dehumidifier is connected to the input end of the hot air blower, the output end of the hot air blower is connected to the main air flow pipe 201, the bottom of the main air flow pipe 201 is blocked, and a discharge valve is installed at the bottom of the drying tank 101 to facilitate the subsequent discharge operation;

[0036] When drying the PET slices and cationic slice crystallization materials, the crystallization materials are added into the drying tank 101 through the feed port 102. At the same time, the hot air blower is operated to transport the hot air into the main air flow pipe 201, and flows into the outermost annular heating pipe 203 through multiple branch pipes 202, and then flows into the annular heating pipe 203 through the arc connecting pipe 204, and enters the drying tank 101 through the air inlet 205.

Compared with the traditional structure with only a single hot air inlet, the multiple groups of vertically distributed annular heating tubes 203 can make the contact between the hot air and the crystallized material more uniform and sufficient, thereby realizing uniform drying of the crystallized material and further improving the drying efficiency.

[0040] A plurality of evenly distributed annular air inlet holes 205 are provided at the bottom of the single annular heating tube 203, and the aperture of the air inlet hole 205 is smaller than the size of the material particles.

[0041] In this embodiment, the arc-shaped connecting pipe 204 has an arc-shaped structure, so that the contact area between the arc-shaped connecting pipe 204 and the crystallized material is larger, thereby assisting in enhancing the heating and drying of the crystallized material. The multiple air inlet holes 205 are provided to allow the hot air to be evenly diffused into the drying tank 101, thereby achieving uniform drying of the crystallized material. In addition, the air inlet holes 205 are distributed downward and the aperture is smaller than the particle size of the material, which can effectively prevent the crystallized material from clogging the air inlet holes 205.
